The latest version of Genefer, v. 3.2.2, has been released and is live for both short and World Record tasks. Some notable changes:

1) The OpenCl and CPU apps are significantly faster than the previous versions.

2) It is likely that the OpenCL app is now faster than the CUDA app on any Nvidia GPU, but especially on newer (Kepler or later, 6xx or newer) GPUs. On the app selection page, the OpenCL app now appears before the CUDA app. NOTE: On Nvidia cards, the OpenCL driver hogs a CPU core. If you have an Nvidia GPU, you may chose between the faster app (OpenCL) or that app that uses very little CPU (CUDA).

3) The CPU app now supports the FMA3 instructions on Intel Haswell CPUs, which makes them even faster.

4) The bug in the Mac ATI app has been fixed.
